Techniques for storing and reading data on/from a hard disk are disclosed. According to one aspect of the present invention, a hard disk is provided with a parameter storage block for storing a number of parameters. One of the parameters is a last physical address the hard disk was accessed. The last physical address is used as a reference to read data segments onto the hard disk. Each of the data segments is a compressed version of a portion of data to be stored in the hard disk. A portion of the data is allocated in accordance with a predefined time period. Accordingly, the compressed data portion also includes a header including information about the compressed data portion. The information includes at least a compression scheme used as well as the time about the data portion. Based on how the data is stored, a corresponding reading method is also provided.
